2008 Proceedings of the 8th ACM/IEEE-CS joint conference on Digital libraries - JCDL '08  
The proposed algorithm identifies a 2-D plot and extracts the axis labels, legend and the data points from the 2-D plot. We also segregate overlapping shapes that correspond to different data points.  ...  We propose a framework based on image analysis and machine learning to extract information from 2-D plot images and store them in a database.  ...  To extract data precisely from figures in digital documents, one must segregate the overlapping shapes and identify the shape and the center of mass of each overlapping data point.  ...

Blind Decomposition of Spectral Imaging Microscopy: A Study on Artificial and Real Test Data [chapter]

Fabian J. Theis, Richard Neher, Andre Zeug
2009 Lecture Notes in Computer Science  
In this contribution we analyze the algorithm on two very well controlled real data sets. In the first case, known sources are artificially mixed in varying mixing conditions.  ...  In the second case, fluorescent beads are used to generate well behaved mixing situations. In both cases we can successfully extract the original sources.  ...  Here the superposition of dyes can be nicely found in the projection: Data points are not only found at the corners of the simplex, but also at the middle of the sides for data points with two dyes, and  ...

Disentangling co-occurrence patterns in n-partite ecosystems [article]

Albert Solé-Ribalta, Claudio J. Tessone, Carlo G. Ferrari, Javier Borge-Holthoefer
2018 arXiv   pre-print
The need to harmonise apparently irreconcilable arrangements in an ecosystem --nestedness and segregation-- has triggered so far different strategies.  ...  Here we question this partial-view paradigm, and show that nestedness and segregation may coexist across a varied range of scenarios.  ...  are in place (segregation in the G P L and G AL projections).  ...

2011 Metabolomics  
This study aims to provide evidence of transgressive segregation in the expression of primary and secondary metabolites in hybrids between Jacobaea vulgaris and J. aquaticus using an NMR-based metabolomic  ...  Expression of a number of primary and secondary metabolites, including jacaronone analogues, chlorogenic acid, sucrose, glucose, malic acid, and two amino acids was extreme in some F 2 hybrid genotypes  ...  Thus for NMR data, loading plots can be used to detect the spectral regions and their corresponding metabolites responsible for the separation in the data.  ...

Musical instrument identification using Principal Component Analysis and Multi-Layered Perceptrons

Roisin Loughran, Jacqueline Walker, Michael O'Neill, Marion O'Farrell
2008 2008 International Conference on Audio, Language and Image Processing  
These features are reduced using Principal Component Analysis and the resultant data is used to train a Multi-Layered Perceptron.  ...  This study aims to create an automatic musical instrument classifier by extracting audio features from real sample sounds.  ...  The violin and flute samples also segregate, but there is some overlap between the two. Hence another feature is needed to distinguish these instruments distinctly.  ...

Functional and structural segregation of overlapping helices in HIV-1

Maliheh Safari, Bhargavi Jayaraman, Shumin Yang, Cynthia Smith, Jason D Fernandes, Alan D Frankel
2022 eLife  
We use a combination of sequence analysis, functional assays and selection experiments to examine an overlapped region in HIV-1 that encodes helical regions in both Env and Rev.  ...  We find that functional segregation occurs even in this overlap, with each protein spacing its functional residues in a manner that allows a mutable non-binding face of one helix to encode important functional  ...  This work was supported by NIH grant P50AI150476, and MS was supported in part by NIH training grant T32AI0605357.  ...

2004 Europhysics letters  
Finally, we draw some analogies between segregation in our granular system and self-assembly in binary colloidal mixtures.  ...  We identified them as a binary gas, segregation liquid and segregation crystal and provide both microscopic and macroscopic measures to identify their properties.  ...  A reasonable approximation to a two-dimensional system was achieved, as only a small degree of overlap of the poppy seeds occurred.  ...
